CNC Operator Trade Career Profile

ROLE OVERVIEW:
CNC Operators load raw materials, offset dimensions, change cutting tools, and run computer numerical control machining centers.

SKILLS REQUIRED:
- Loading raw castings and components into jigs/fixtures
- Monitoring and adjusting tool wear offsets
- Checking tool inserts and replacing worn cutters
- Inspecting finished parts using vernier calipers

TOOLS USED:
- CNC lathe and vertical machining center (VMC) machines
- Micrometers, verniers, thread rings, and tool height presets
- Allen keys, wrenches, and tool clamping blocks
- Pliers, spanners, and screwdrivers

GROWTH PROSPECTS:
Foundation technical training leading to CNC programmer and tool setting paths.

INTERVIEW QUESTIONS:
1. Q: What does VMC stand for and how is it different from a CNC lathe?
A: VMC stands for Vertical Machining Center, which rotates the tool against a fixed work; a CNC lathe rotates the work against a fixed tool.
2. Q: How do you adjust a wear offset on a CNC controller?
A: Measure the machined part dimension, compare it to the target drawing, access the offset page on the controller, and input the difference in the wear register.
